Re: EEC V file conversion

the v10 trucks use a similar ecu but none are an exact match

problem with the harley/lightning ecu is there aren't many outputs that aren't used. There are no eec-v ecu's with more hardware as it uses all of it.

you can use the ic output for fan control if you wanted and just hook up the ic pump to the fuel pump trigger.

yeah its easy enough to write the code using a hex editor. I use tunerpro and just write the code using a patch makes life simple.

If you can read code you can write code nothing to it really just time consuming.

Re: [GUFX] Strategy Files

Updated a9l2 and gufx posted. FN111 revamped, all dashpot is now rpm error based and corrected some lookup malfunctions on fn338, fn320 and the like.

Re: 400hp 351w startup tune

pull 15 degrees out right there and it should make significantly more power

Re: 400hp 351w startup tune

that looks horrible

41 degrees at wot between 1250 and 1750 rpm is significantly over advanced

the mbt guidance on the homepage would get you much more in the ballpark

Re: Are newer Ford MAF's all 5v Reference

read the maf write up

its ground reference -5v not positive

the ecu is expecting a period freuquency input not voltage as the maf electronics does the conversion

Re: Clearing a Flooded Engine w/ the MAF Table?

You can actally put the maf in upside down and it will still work

seen someone do that once

not recommended but appeared to work fine

those look like the valve covers off the 351w trucks.

Re: Clearing a Flooded Engine w/ the MAF Table?

I have no idea what your trying to describe about the maf but the ecu uses the top point for lookup and works down. Its the same for eec 5 as it is eec 4.

1023 23
0 20 <--- zero ends the maf curve
below no longer exists and is no longer part of the maf curve regardless of what you put in there.
900 1600
850 1400
800 ....

the above is a valid and non corrupt maf transfer.
You cant have any lower x axis value higher than the above value or it will corrupt. But 0 ends the maf transfer.

ex:
1023 23
1 20
900 1600 << will corrupt the maf.

remember all x axis need to be maximum to minimum values in chronological order for all functions otherwise youll corrupt it.

No, the reason why your maf is inverted is because you didnt setup tunerpro correctly per the getting started write up.
